Definitions

  • the present invention relates to an elevator system with an elevator belt, an elevator belt for such an elevator system and a method for producing such an elevator belt.
  • An elevator installation comprises an elevator cage and, as a rule, a counterweight, which are movable in an elevator shaft or along free-standing guide devices.
  • the elevator installation has at least one drive with at least one drive wheel each, which carries the elevator car and the counterweight via one or more belts and / or transmits the required drive forces thereto.
  • a drive wheel can be designed in a manner known per se as a traction sheave or equally as a wheel with a smaller diameter, in particular as an output shaft of the drive itself.
  • the elevator car and the counterweight may be carried and driven via the same at least one support and drive belt, which is guided over the at least one drive wheel.
  • the elevator car and the counterweight can also be coupled to one another via at least one carrying belt, so that the counterweight lifts when the elevator car is lowered and vice versa, wherein the drive of the elevator car and the counterweight by a drive unit via at least one separate Drive belt is done.
  • driving belts are transmitted by drive wheels on drive belts to move the elevator car or the counterweight, Are pure strap not deflected by driving wheels, but only deflecting elements, in particular rotatable or fixed pulleys and take the weight of the elevator car or the counterweight on.
  • the support and the drive function are met by the same at least one support and drive belt.
  • An elevator belt according to the present invention can be used for any of the functions described above, ie equally as a carrying strap, as a drive belt or as a support and drive belt, as one of a plurality of parallel belts or as a single belt.
  • pulleys where no distinction is required between driving wheels and pulleys, these are hereinafter generally referred to as pulleys.
  • an elevator belt according to the preamble of claim 1 is known with a belt body made of polyurethane, in which a Switzerlandtownan extract is arranged with ropes of multi-twisted wires for transmitting a tensile force in the longitudinal direction of the elevator belt.
  • the individual tension members can shift relative to each other. This can lead to an unfavorable arrangement of the tension members in the transverse direction of the belt.
  • two tensile carriers may lie closely adjacent in the belt body or even touch each other. Since the tension members in the wrapping of a pulley, in particular a drive wheel by the tensile forces transmitted by them in part considerable compressive stresses on the Exercise belt body, there is a risk that the belt body is damaged by the increased local load, which occurs in closely adjacent, in particular contacting tension members. In extreme cases, closely spaced tension members can cut through the belt body.
  • US 4078443 is a drive belt with tension members known.
  • the tensile carriers can be enclosed in a stiffening element, or alternatively glued to a stiffening element.
  • AU 24687 71 A is a suspension means described which can be used for elevator systems.
  • This support means has parallel tension members, wherein the opposing surfaces of the support means are protected with elastomeric material.
  • several layers of parallel tension members can be arranged one above the other, wherein the individual layers are separated from each other by strips of elastomeric material.
  • WO 2005/054569 A2 is a tension member known which comprises at least one strand of rope tensile material.
  • the central strand of this stranded strand may be enveloped by a flexible thermoplastic layer, so that the central strand is connected to the peripheral strands of this Kuststoff Anlagen.
  • US 4773896 is a V-shaped drive belt known.
  • This belt has longitudinally extending reinforcing elements, which may be made of metal, glass fiber, or material with similar Rezssfesttechnik.
  • An object of the present invention is therefore to provide an elevator belt in which the positioning of the tension members within the belt body is improved.
  • an elevator belt according to the preamble of claim 1 is further developed by its characterizing features.
  • Claim 13 provides the associated manufacturing method and claim 16 an elevator system with such an elevator belt under protection.

  • the tension members of the tension member assembly comprise strands or ropes, preferably of wires or plastic fiber yarns, more preferably of steel wires. Between at least two adjacent ones Tensile members of the tension member assembly, a flexible profile body is arranged, which spaced these tension members to each other.
  • a minimum distance between the two tension members can be specified to each other during the manufacturing process. In this way it can be avoided that the two tension members in the ready-to-use elevator belt are too close to each other or even touch one another, which would lead to an inhomogeneous distribution of forces in the elevator belt and a locally higher load on the belt body.
  • the two adjacent tension members lie positively against the intermediate profile body, so that their mutual relative position is predetermined with high accuracy.
  • at least one profile body is arranged between a plurality, more preferably between all tension members of the tension member arrangement.
  • the tension member assembly as a whole can be positioned in the correct position in the belt body. If, for example, in the case of belt production in the extrusion process, tensile carriers and profile bodies are fed side by side continuously and in the correct position to the belt extrusion tool and embedded in an extruded belt body, the profile bodies prevent greater deviations of the tensile carriers from their intended position in the belt body.
  • the positive support of adjacent tensile carriers to the intermediate profile bodies stiffen the elevator belt in the transverse direction, which on the one hand counteracts a deformation of the elevator belt under longitudinal load and on the other hand ensures the dimensional stability of the belt cross-section, when the elevator belt must rotate between two pulleys of a lift system about its longitudinal axis.
  • profile bodies on the same cross-section, which allows an equidistant distribution of the tension members and the formation of a homogeneous elevator belt.
  • cost for the production and storage of the profile body as well as for their positionally correct arrangement during the manufacturing process since it does not have to pay attention to which profile body is to be arranged between which tension members.
  • At least two profile bodies may have different cross-sectional shapes. This also makes it possible to realize different distances between two tension members.
  • the cross-sectional shapes and / or cross-sectional sizes of the profile body can be adapted to tension members with different outer contour, in particular with different diameters, whereby their mutual positive support is improved.
  • the profile bodies preferably have substantially circular, oval, T-shaped, double-T-shaped, U-shaped, triangular and / or quadrangular cross-sections.
  • Geometrically simple cross-sectional shapes such as circular, oval, triangular or quadrangular cross-sections are easy to produce, for example by extrusion.
  • point-symmetrical cross-sections in particular in the case of round or square cross-sections, it is not necessary to pay attention to an orientation-correct placement of the profiled bodies during the production process.

  • the profile bodies preferably extend in the longitudinal direction of the elevator belt substantially over the entire length of the elevator belt, advantageously parallel to the tension carriers.
  • the profile bodies are preferably made of a thermoplastic plastic, in particular polyamide (PA), polyethylene (PE), polyester, in particular polyethylene terephthalate (PET) and / or polycarbonate (PC), polypropylene (PP), polybutylene terephthalate (PBT), polyethersulfone (PES), Polytetrafluoroethylene (PTFE), polyvinyl chloride (PVC) or a polyblend made of several thermoplastics.
